What is it?
Hi all,
Can anyone tell me what the 'cone' shaped housing is that is located on the left front and right rear of the engine? I'm asking as I quite obviously don't have a workshop manual.

Can I just remove it or do I need to know something special???

I see your point Del but that's exactly why I am asking. I was also expecting guys in the know like you to answer and not someone who thinks they know what it is. If it is the cam chain tensioner I want to see in what state it is. And that would have been my next question: How do I know if it needs replacement. I'm not gonna go to some so called mechanic that's gonna tell me it needs replacement when it doesn't. What is one supposed to do if you're surrounded by a bunch of workshops who are only interested in your money?

I've tried with the original post and now again but I can't get the picture uploaded so I placed it on myown website and I'm pointing to it from here. Here's the picture of what I'm talking about

Yep thats definately your cam chain tensioner Neo.
Iw ould definately consult your manual before removing as I think (could be very wrong here but...) you need to remove them with the pistons in a certain position, Del will be able to tell you the proceedure I'm sure.

If the engine,s not wrattling or making a slapping sound leave it alone!
If you are getting a slappy type wrattle you can diagnose which tensioner needs replacing by simply sticking the handle of a screw driver in your ear and the other end on each tensioner body in turn. The noisey one will be easier to find that way. (bet it's the front one).
Oh ... and you can take em off just by undoing the bolts at it,s base but without a special little locking plate you won't get them back on very easy,if at all.

Neophyte,
Take a scan back over the posts regarding CCT's in the workshop section and you'll understand what it's all about. By taking it out, you will not be able to see what state it is in. There is an internal spring that fails in it, and unless you have something to analyse the make up of springs, you won't be able to tell. If it is going, there is a slapping noise in the engine, ie the cam chain whipping around inside. If it gets that far, kill it before you bend valves and wreck pistons. Basically if it aint broke...........

It might not be f8cked.
I had one which was getting slappy when the engine was only half warm. The rear aways fills with oil because of the angle of it but the front is nearly virtical so it stays dry inside. Anyway on the inside is a screw slot (about an inch down inside the "cone") if you turn the screw it retracts the tensioner from the chain or ,if left alone, as the chain stretches it should rotate the other way to take up the slack.
My front one got stuck, I guess because it was dry. So I just dribbled a little oil down the hole, screwed the tensioner fully retracted and just let go. Did this a couple of times,just to be sure the adjuster mech was operating smoothly again and kerching. One fully functional tensioner
Oh, by the way. If you are going to try this you should know that the washer on the end of the tensioner is a special "crush" type and is supposed to be replaced once it has been removed.(but if you are careful with it it should be ok for a second go)

If your going to attempt to test the spring is working then the cylinder your going to test must be at TDC on the compression stroke. If not then the cam chain tensioner will just retract as you turn the screw driver because the cam chain will be kept taught by the open valve/valves.
Also the crank will only be at TDC on the compression stroke every 720 Degrees and not every time the FT is seen in the inspection window.
